Cap



Patented July 18, 1933 UNITED STATES ANTHONY ZAYV, OF CLEVELAND, OHIO CAP lapplicati@ flied August 27, 1931; semi No. 559,754.

My present invention pertains to a cap that affords a closure for various types of receptacles or the like, as for inst-ance the cap for the radiator of an automobile, for the filler spout of an automobile gas tank, for a jar or for any other article containingliquids in which cap is employed for closing or sealing the same, and the primary object is the provision of a cap for this purpose which may be readily applied and effectively locked upon the receptacle to prevent the spilling-of the contents thereof, toobviate the liability of displacement of the cap regardless of the vibration to which the same may be subjected and to likewise afford a sealed joint between the cap and the receptacle.

The invention will be fully and comprehen-v sively understood from a consideration of the following detailed description when read in connection with the accompanying drawing which forms part of the application, with the understanding., however,that the im,- provement is capable of extended'application and is not confined to the exact showing of the drawing nor to the precise construction described and, therefore, such changes and modifications may be made therefrom as do not affect the spirit of the invention nor eX- ceed the scope thereof as expressed in the appended claims.

In the drawing:

Figure l is a sectional viewy through the improvement arranged upon the neck or spout of a receptacle.

Figure 2 is a similar view but showingthe cap locked on the receptacle,

Figure 3 is a bottom plan view of the cap.

Figure 4 is aside or edge view of the head and lever elements of the improvement. Figure 5 is a plan view of one of the lock plates. y y f *While my improvement is admirably adapted for use in connection with the radiators and gasoline supply tanks for automobiles, and is primarily designed for employment ink such connections thev i'mprotement is not to be restricted in its useful capacity as a closing element for any particular' type of receptacle. It will be noted as the description progresses that when in applied position the cap not only effectively seals the receptacle but'cannot bedisplaced therefrom regardless of .any vibration to which the same is subjected. i l Referring now to the drawingin detail the 5t' .numeral l designates the neck or inlet spout for a liquid containing receptacle. The neck, at its outer end, is formed with an inwardly extending lip 2. Y t, The cap 3 may and preferably is of ordi'- 6o nary type to include a round top provided with a depending flange, but the flange in this i instance has no threaded engagement with the neck l.y ln the cap 8 there is a compresv sible washer 4 which is in the nature of a disc 65 or ring and which is in direct contact with the'lip 2 when'the cap is applied. rlhe ring or disc' washer 4, in the showing of the drawing, rests against a metal plate or disc 5 which contacts with the inner face of the cap To and is frictionally or otherwise secured therein. j

Aperipherally grooved boss 6'y is secured in a central opening in the top of the cap 3 to project both inwardly and outwardly therefrom and the said -boss may besecured to the disc 5. The boss Gis provided with a central substantially rectangular opening ythrough which passes the straight and central arm 7 ,j on a head vmember 8. The head is in the nature of a flat plate which is somewhat elongated and which has its ends vcurved or rounded, as at 9. The inner edge of the plate, adjacent to the rounded endsthereof, is formed 4 with flat extensions in the nature of fingers S5" 10 which are of al length materially less than that of the Aarm 7. Each'nger 10 is designed to pass through a substantially rectangular y opening ll in a lock plate 12. The slots 'or y openings-l1 of the lock plates l2 are arranged 30 adj aeent to what I will term the inner ends ofsuch plates'and las the fingerslO freely pass through the said openings 11 the plates will naturally gravitate on the said fingers to assume the inclined positions disclosed by 8F* Figure l of thedrawing and whereby the outer or active ends of the said plates are sustained away from the lip 2 of the neck l-to permit of the cap 3 being freely arranged on the neck and likewise to permit of the lock EGG plates being disposed below the lip. The disk 5 is provided with slots or openings 13 whose walls afford guides for the fingers 10, and there is removably pivoted as at 14:, to the outer or projecting end of the arm 7 a bifurcated lever 15.

In order to urge the lockplates 12 to their angular positions on the head 8 there is centrally arranged on the arm 7 a spring plate 16 that has oppcsitely directed downwardly arched arms 17 that are in contact with the respective lock plates 12. n

The lever 15 is struck from a single plate which is bent upon itself, the saidbent portion being widened, rounded and provided with a central concaved end 18 that aords oppositely directed finger grips 19, respectively, and when the cap is in position and the lever swung on its pivot 14 to raise the head 8 and to force the lock plates 12 into locking engagement with the lip 2, one of these grips 19 are in contacting engagement with the outer face of the cap.

rEhe inner corners of the lever 15 are rounded so that thesame may freely ride over the outer face of the boss 6 when the lever is swung to lock the cap in the neck. By providing the removable pivot 14 the lever can be readily removed from the arm 7 and all of the parts of thev improvement may be removed from the cap. This, of course, is only necessary in case of breakage of some of the parts and the parts are of such construction that the same are not liable to easy breakage. The pivot 14 may be in the natu-re of a `rivet to prevent the surreptitious separation of the lever from the arm and there may be fixed on the top of the cap a bracket or bail 19 to be received between the arms of the lever and to register with openingsin the said arms when the lever is swung to locking position, and through these registering openings there maybe passed the hasp of a padlock 20 which effectively locks the cap on the neck, 1. Having describedthe invention, I claim:

1'. ln a cap for acontainer, the latter having a neck with an inwardly extending lip, a headarranged in the cap, van arm formed with and rising from said l,head and extending through the cap, lock plates swingably carried by the head and normally disposed to pass into the neckbelow the lip, a lever pivotally secured to the outer end of the arm and being swingable at right angles with re.- spect to the latter and against the cap to impart an upward movement to the head for forcing the lock plates in gripping engagement with `the lip, anda washer in the cap andfengageable with the lip to provide a leak proof rconnectionv between the'cap and lip.

2. In a cap fora container, thelatter having a `neck with aninwardly extending lip, a head arrangedin the cap, fingers formed on said head and rising therefrom, an arm kformed on said head and rising centrally therefrom, said arm passing through the cap, lock plates having openings adjacent one of ,their ends for loosely andslidably receiving the fingers to permit the lock plates to normally assume a position to freely enter the neck below the lip, an arched spring mounted on the arms and fingers and contactingl the lock plates to hold the latter under tension, and a lever pivotally secured to thefouter end of the arm and adapted when swung against the cap to move the head upwardly for forcing the lock plates in gripping engagement with the lip to secure the cap to the neck. v

3. In a cap for a container, the latter having a neck with an inwardly directed lip, a disk in said cap, an elongated fiat head arranged in the cap, lingers formed on and rising from the head and mounted for slidable movement `in said disk, an armV formed on and rising centrally from the head, said arm iassing throughthe cap, lock plates having openings adjacent one of their ends through which the fingers freely pass to permit the lock plates to normally assume a position for allowing the latter to freely enter the neck below the lip, a lever pivotally secured to the .upper end of the arm and movable laterally in either direction against the cap to draw the head upwardly and to force the lock plates in gripping engagement with the lip for securing the cap to the neck and means for locking the lever against thecap with the lock plates in operative position.

et. In a cap'for acontainer, the latter having a neck provided with an'inwardly directed lip, a head arranged in said cap, fingers formed on the head and rising therefrom, an arm formed on the head and rising centrally therefrom between the fingers, a boss secured in the top .of said cap and having an opening for the passage ofthe armV there.- through, lock plates loosely mounted on the fingers to permit the lock plates to-normally assume aposition yfor allowing them to freely enter the neck for disposal below the lip, spring means Carried by the head vand engageable with the lock plates to hold the latter Vunder tension, a lever pivotally secured to the upper end of the arm and having a widened forked upper end to provide finger grips, and said lever being movable on its pivot laterally in either direction for drawing the head upwardly through the medium of the yarm for forcing the lock platesin gripping engagement with the lip, anda gasket arranged in said cap and engageable with the neck to provide a leak proof connection between the lcap and neck.
